What is a complete solution to the equation (x -10) (x + 8) =0?

Answer 1

x-10=0 means x=10
x+8=0 means x=-8
-8 and 10 are solutions.

Answer 2

x-10=0 and x+8=0 so x=10 or -8

Answer 3

(x -10) (x + 8) =0?

(x -10) =0 ->
x=10

(x + 8) =0->
or x=-8

(10,-8)
To verify plug in one of the solutions at the time and see if they are true.

(10 -10) (x + 8) =0 ->
0 * (10+8) = 0 one correct solution

(-8 -10) (-8 + 8) =0 ->
(-8-10) * 0 = 0 2nd correct solution

Answer 4

x = 10 , x = - 8

Answer 5

set each factor equal to zero (i.e x - 10 = 0 & x + 8 = 0), then solve for x in each one which leads you to the final solution of 10 & -8

Answer 6

x can equal 10 or -8, because that would make one of them 0, and multiplying anything by 0 gives you 0

Answer 7

(x -10) (x + 8) =0?


x=10 or x= -8


(just examine each term independantly ie
x-10=0 and x+8=0 )

Answer 8

i.(x-10)(x+8)=0
ii. x2 - 10x + 8x - 80 = 0 [FOIL method]
iii. x2 - 2x - 80 = 0
iv. (x - 10)(x + 8) = 0
v. x - 10 = 0 ; x + 8 = 0
vi. x = 10 ; x = -8

SS: {10,-8}

Or just simply do iv, v then vi to get the solution set but that doesn't apply to all.

Answer 9

(x-10)(x+8)=0 so x-10=0 or x+8=0
i) x-10=0 so x=10
ii) x+8=0 so x=-8

so solutions {-8,0}
